CHANGE POINT ANALYSIS FOR SHORT-TERM PROCESS CAPABILITY BASED ON EMPIRICAL LIKELIHOOD METHOD

Abstract
Process capability indices are widely used to assess the process yields. Traditionally, we use only a long-term process capability index value to determine whether the process yield meets the yield requirement, but this will lose many important information of the production. Therefore, change point analysis can monitor the short-term process capability. Bythismethod, not only can we obtain more important information of the production, but also we can immediately correct a bad short-term process capability. This will avoid a long-term process capability. However, these methods are constructed based the normality of the short-term process capability. Therefore, this study applies the concept of empirical likelihood to construct the method of change point analysis for short-term process capability of CPU. The research result can solve the problem of monitoring Ab-normal short-term process capability. Keywords - change point analysis; Process capability.
